Summary:
The maximum value of radiated emission must be measured at a distance of 10m for the CISPR publishes. However, the test facilities are too expensive to measure at a distance of 10m. Therefore, the method has been studied to estimate radiated emissions at a distance of 10m from the measured data at a distance of 3 m. The conventional estimation method considered with three components of current vectors and this need much estimation time. In this paper, we propose the estimation method considering with current and magnetic- current sources. The equipment can be modelled by one component of the current vectors using both current and magnetic-current source, and this method can reduce the estimation time because the estimation parameters reduces from nine to five. The electric field radiated from the imitated equipment was estimated by using numerical calculation value. The results indicated that the accuracy of proposed method was almost equal to conventional method for horizontal polarization, and the estimation time decreased two thirds.
